Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: The integral $\int \int \int (x^2+y^2+z^2)dxdydz$ taken over the volume enclosed by the sphere x2+ y2+z2 = 1 is $\frac{4\pi}{5}$
Reason R: $\int^{1}_{0}\int^{1}_{0}x\ dxdy=\frac{1}{2}$
In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Answer 1

Answer: (B)

Both A and R are correct but R is NOT the correct explanation of A

Answer 2

The correct option is(B):Both A and R are correct but R is NOT the correct explanation of A.
